tobeno1.shop / case for glasses persol 714sm

On 12th January 2019 I ordered a case for glasses Persol 714SM.
I received instead of my order a pair of glasses.
The vendor does not answer to my complaint and no one is giving me a solution.
I only received the following mail from [protected]@tobeno1shop.com inviting me to contact the vendor (Dear, Sorry for the inconvenience that have caused you.Please contact the merchant as soon as possible, the email address is [protected]@gmail.com
Best regards.)

I need a refund cause I cannot use the glasses received.
the internet site www.allegrotrenino.it where I have placed the order is no more usable!!!
